The appimage is created and I can run it
But, I have some issues that I am not able to solve:Issue 1:
When I do on the “Skrooge dashboard”, the QML widgets are not displayed and I have the following traces in the console:

Thank you for this quick answer.
I tried to build the appimage.
I did:
./linuxdeployqt-continuous-x86_64.AppImage skrooge/build/appdir/usr/share/applications/.desktop -bundle-non-qt-libs
./linuxdeployqt-continuous-x86_64.AppImage skrooge/build/appdir/usr/share/applications/.desktop -appimage

But, when I launch the image, the skrooge plugins are not loaded. Do you have an idea?

Do you know why the libqca-ossl.so is searched on my system and not on the image?

libqca-ossl.so is in a non-standard location inside the AppImage (not in usr/lib or usr/lib/x86_64-linux-gnu) so the application does not know where it has to search for it. It might work if you move it (and any other libraries that are currently in subdirectories of usr/lib or usr/lib/x86_64-linux-gnu) there.

Is this correct or are there icons missing? If yes, make sure that the application looks for them in relative paths (relative to the application itself) rather than in absolute paths that are hardcoded at compile time (e.g., $PREFIX).

Icons are loaded by using KDE API( example: KDE::icon(“edit-undo”) ).
They are normally searched in standard directories and loaded.
They should be found in /usr/share/icons which is in the appimage.
